Guide to Operation

54-0198

1 System Overview

A complete satellite TV system, illustrated in Figure 1, includes the TracVision G8 antenna unit connected to the Master Control Unit (MCU), an IRD (satellite TV receiver), and a television set.

System Compatibility

The TracVision G8 is fully compatible with Digital Video Broadcasting (DVB

) satellites, as well as DIRECTV®‘s Digital Satellite Service (DSS) satellites. The system is also fully compatible with KVH’s TracNet

™

2.0 Mobile High-speed Internet

System (for more information about TracNet 2.0, please visit our web site at www.kvh.com).

In-motion Tracking

The TracVision G8 uses a state-of-the-art actively stabilized antenna system. The antenna’s built-in global positioning system (GPS) allows the system to calculate the precise azimuth and elevation to the satellite from your vessel’s current location, ensuring the shortest possible satellite acquisition time. Once the satellite is acquired, the antenna gyros continuously measure the heading, pitch, and roll of your vessel and send commands to the antenna motors to keep the antenna pointed at the satellite at all times.

Satellite Library

Your TracVision G8 includes a pre-programmed satellite library of North American, European, and Latin American satellite services. If the satellite service you wish to receive is not already in the satellite library, an authorized technician can add two additional satellites of your choice to the library.

System Components

Your TracVision G8 system includes the following components:

Antenna Unit

The antenna unit houses the antenna positioning mechanism, low noise block (LNB), GPS, and three-axis sensor within a molded ABS radome. The European version includes a skew control mechanism that automatically adjusts the antenna’s skew to account for regional changes and different satellite services. Power, signal, and control cabling from belowdecks units are connected to the antenna at the rear of the baseplate.

Master Control Unit

The MCU is the user interface, providing access to the system and its functions through an LCD and three soft keys. The MCU also serves as the system’s junction box, allowing the system to use ship’s power and supply and receive data to/from the TracVision G8. The MCU can accept any power input between 9 and 36 volts DC; its power supply provides power to the antenna and galvanically isolates the TracVision G8 system.

Integrated Receiver Decoder (IRD)

The IRD (purchased separately) receives satellite signals from the antenna unit for signal processing and channel selection, and sends the signals to the TV set for viewing. Please refer to the user’s manual provided with your selected IRD for complete operating instructions.

Guide to Operation

54-0198

2 Receiving Satellite Signals

For TracVision G8 to receive satellite TV signals, the antenna must have a clear line of sight to the satellite. If you only receive intermittent signals or the antenna cannot find the satellite, check around your vessel for any objects that could be blocking the signal, such as other vessels, trees, buildings, other onboard equipment, etc.

You must also be located within the selected satellite’s coverage area in order to receive its signal. Refer to your satellite television service manual to check the viable coverage area. For your

convenience, KVH provides links to several web sites that offer satellite coverage information. Simply go to our web site at: www.kvh.com/

footprint/index.html.

3Turning On the System

The TracVision G8 system is easy to use. Antenna unit initialization and satellite acquisition are completely automatic.

To use the TracVision G8 system, follow the steps below.

1. Turn on the IRD and the television. (Refer to your

IRD user’s manual for complete operating instructions for the IRD.)

2. Apply power to the TracVision G8 antenna.

3. Minimize turning the vessel for two minutes after turning on the antenna to allow the antenna gyro to initialize properly.

To minimize the time it takes the antenna to acquire the satellite, do not change the channel during the startup process or cable unwrap.

Guide to Operation

54-0198

4 Changing Channels and

Switching to the Second Satellite

TracVision G8 can have a pair of satellites installed, either one of which can be the active satellite selection. There are several methods of selecting whether your TracVision G8 will track Satellite A or Satellite B based upon your location, type of install, IRD, and selected satellite service.

European Satellite Subscribers

If you are not using a multiswitch, switching from one satellite to the other is as easy as changing the channel using the IRD remote control. TracVision G8 will automatically switch from Satellite A to Satellite B and back again as necessary to receive your selected channel. If you are using a multiswitch, use the MCU switching option described in “Switching Satellites Using the MCU” on

page 8.

DIRECTV Satellite Subscribers

DIRECTV subscribers in certain regions of the United States will require a DSS Plus

™

IRD to receive broadcasts from multiple

satellites.

If connected to the antenna’s RF1 connector, the DSS Plus IRD allows you to switch channels using the IRD remote control. If you are a DIRECTV subscriber, but do not have a DSS Plus IRD, or you are using a multiswitch, use the MCU switching option described in “Switching Satellites Using the MCU” on page 8.

EchoStar and ExpressVu Satellite Subscribers

EchoStar and ExpressVu subscribers will need to use the MCU switching option, as described in “Switching Satellites Using the

MCU” on page 8.

DIRECTV Latin America Subscribers

If your TracVision G8 is equipped for use with the DIRECTV Latin America service, your antenna will search for and receive signals from one satellite (Galaxy 8W or Galaxy 8E). Therefore, there is no need to switch satellites.

The satellite configuration on your IRD must match the satellite setting on the TracVision G8 system.

Satellite A on the TracVision G8 must be the same satellite as IRD Alternative 1 (or A, based on your IRD) and must be assigned the IRD DiSEqC 1 setting.*

Satellite B on the TracVision G8 must be the same satellite as IRD Alternative 2 (or B, based on your IRD) and must be assigned the IRD DiSEqC 2 setting.*

Refer to your IRD user manual for complete instructions for your IRD.

*DiSEqC settings only apply to European systems and DIRECTV DSS Plus

™

IRDs.

When you switch from one satellite to another, all IRDs connected to the system will receive signals from the new satellite.

54-0198

TracVision G8 Owner’s Manual - Guide to Operation

Switching Satellites Using the MCU

If you’re unable to switch between satellites using the IRD remote control, use the MCU front panel buttons to select between Satellite A and Satellite B. Press the left button to select Satellite A and the right button to select Satellite B.

5Watching Television

TracVision G8 is designed to operate as efficiently and as reliably as possible both when your vessel is in motion and at rest.

Cable Unwrap

The antenna can rotate a full 720° before reaching the end of its cable. If it does so, the system automatically unwraps the cable by quickly rotating the dish in the opposite direction. During this time, your television transmission will freeze momentarily while the cable unwraps and the antenna reacquires the satellite.

Conical Scan Tracking

The antenna uses conical scanning to maintain peak signal strength to the receiver and to update the satellite’s position. When conical scan tracking is active, the antenna moves continually in a circular motion to sweep across the satellite’s peak signal. The signal strength is then fed back to the control circuits to keep pointed in the direction of the strongest signal.

If the satellite signal is lost while the system is in conical scan track mode, the control software imposes a 15-second time-out delay. If the signal is not regained during that time, the antenna will search for the satellite signal. This is an automatic process that does not require user intervention.

Sleep Mode

When the vessel has come to a stop and holds its position for one minute (e.g., at a dock), the antenna unit enters Sleep Mode, which locks the antenna in place to conserve power. As soon as the vessel moves beyond a 1° - 2° window, or the RF level changes significantly, Sleep Mode automatically turns off and the system begins tracking the satellite again (or enters Search mode to find the satellite).

6 Internet Access

Your TracVision G8 can receive high-speed Internet data when used in conjunction with KVH’s TracNet 2.0 Mobile High-speed Internet System. With TracNet 2.0, you get broadband Internet access on the move via satellite downloads and a wireless return path. For more information about TracNet 2.0 in North America and Europe, please visit our web site at www.kvh.com.

If you prefer, you may disable the Sleep Mode function. Refer to

“Turning Sleep Mode On/Off” on page 70 for details.

2.1 Planning the Installation

Who Should Install the TracVision G8

KVH recommends that a KVH-authorized technician install the TracVision G8 system. Installers should have experience installing electronic equipment on a vessel.

Materials and Equipment Required for Installation

Before you begin installing the TracVision G8 system, you need to verify that you have all of the following tools and materials:

• Electric drill and

⁄2" (13 mm) drill bit

• 17 mm socket wrench

•

⁄

16" open-end wrench

• Flat head and Phillips screwdrivers

• Light hammer; center punch; tape; scriber/pencil

•Wire strippers

• A PC with terminal emulation software such as

Windows Hyperterminal or PROCOMM

• Quick-tripping circuit breaker or fuse rated for 30 amps

• RG-11 cable(s) with F-type connectors (refer to

Table 2-1 to determine the number of RF cables needed)

Connecting to: # RF Cables

North American Systems

One IRD 1 Two IRDs 2 Two or more IRDs 2*

European Systems

One IRD 1 Two IRDs 2 Three IRDs 3 Four IRDs 4 More than four IRDs 4*

* Multiswitch required. Follow manufacturer’s guidelines.

Table 2-1

Number of RF Cables to Connect to the Antenna

RG-11 with F-type connectors is required for all RF wiring. Use of any other cable will result in degraded performance, which is not covered by the KVH warranty.

You may want to connect four RF cables to the antenna in all cases. That way, if an IRD is added (or the system is converted from North American to European use) in the future, no additional RF cables will need to be run.

Plan the entire installation before proceeding! Take into account antenna unit placement, cable running distances between units, and accessibility to the equipment after installation.

If you are prewiring the system, be sure to route the N-type connector end of the data/power cable to the antenna location and the F-type connector end to the belowdecks MCU (see Figure 2-8

on page 28).

• Power cable to connect the MCU to ship’s power (Table 2-2 provides proper gauge and length specifications for a 12V supply. The system will not work if the MCU receives less than 9V).

Recommended MCU-to-Ship’s

Power Cable Specifications

Choosing Component Locations

When determining component locations, first keep in mind accessibility and cable lengths between units. For example, since the data/power cable is 100 ft (30 m) long, the MCU must be located within 100 ft (30 m) of the antenna.

The major considerations in locating the TracVision components are described below.

Choosing the Best Location for the TracVision Antenna

There are several factors to consider when choosing the location for the TracVision antenna.

• Since the TracVision antenna requires a clear view of the southern sky to receive satellite signals, the ideal antenna site has an unobstructed view of the horizon/satellite all around. The less blockage, the better the system performs.

• Keep the antenna clear of any obstructions above decks. The antenna requires a -15º to +85º look angle to receive satellite signals.

• To minimize tracking errors, place the antenna

unit as close as possible to the intersection of the vessel’s fore-and-aft centerline and midships. The antenna unit need not be located exactly on the vessel’s fore-and-aft axis, but its centerline MUST be parallel to it.

Installation

54-0198

Figure 2-1

Antenna Blockage

Mast

Vessel Platform

TracVision Antenna

• The mounting surface should be flat and strong

enough to carry the complete assembly (85 lbs/

38.6 kg). To prevent warpage to the antenna baseplate, make sure that the mounting surface is rigid so that it cannot flex when the vessel vibrates. If necessary, add a strength member to the mounting site to stiffen it.

• Be sure to account for the height and base dimensions (see Figure 2-2 on the following page). Also be sure to leave enough space outside the access hatch to allow a technician to remove the seven hatch screws and perform maintenance through the hatch.

• Maintain at least four feet (1.3 m) separation

between the antenna and any magnetized materials, large ferrous masses, cranes, engines, derricks, other antennas, cables carrying high amperage direct current, or battery banks. Take extra care when mounting the antenna on a steel vessel; use an aluminum, brass, plastic, or wood (NOT steel or iron) platform to position the antenna at least four feet (1.2 m) above and six feet (1.8 m) away from the steel surface.

• Be alert for devices that change their magnetic

characteristics when in use, such as CRTs (computer and TV screens), radar magnetrons, electric winches, loudspeakers, windshield wipers, and other devices with DC motors. The antenna’s internal sensor cannot compensate for changing magnetic fields created by these devices.

Radar Concerns

The TracVision antenna must be kept out of line with nearby radars, as their energy levels (from both the main beam and its side lobes) may overload the antenna’s front-end circuits. In an ideal installation, the antenna is mounted four feet (1.2 m) above and four feet (1.2 m) away from the radar (measured from the center of the antenna dome to the center of the radar).

The best placement for the TracVision antenna is above the radar. However, if there will be a significant horizontal separation between the radar and TracVision dome (i.e., at least 8 to 10 feet (2.4 to 3 meters)), the TracVision antenna can be placed below the radar as there will be little chance of signal blockage.

54-0198

TracVision G8 Owner’s Manual - Guide to Technical Information

Choosing the Best Location for the MCU

• The MCU should be mounted in a dry location, allowing enough room at the back for connecting system cables.

• The MCU should be placed so that the LCD display is visible and the buttons are accessible to the user.

• The MCU is not susceptible to magnetic interference and does not need to be mounted on a level surface.

2.2 Mounting the TracVision Antenna

1. Make sure that you have chosen a suitable mounting location based upon the guidelines in

“Choosing the Best Location for the TracVision

Antenna” on page 23.

2. Using the template provided at the back of this manual or the dimensions shown in Figure 2-3, lay out the four mounting bolt holes. Make certain that the “Forward” arrow is parallel with the vessel’s centerline and pointed toward the bow.

3. Drill the four

⁄2

" (13 mm) bolt holes following the

layout in Step 2.

4. If mounting the antenna on a deck: Mark a location aft of the antenna for the cable access hole. The hole must be large enough to accommodate the data/power cable and all required RF cables (see Table 2-1 on page 21 to determine the number of RF cables required). Cut out the access hole and smooth the edges of the hole to protect the cables.

5. Remove the antenna unit from its shipping carton.

2.3 Connecting the IRD(s)

Connecting the RF Cable(s)

Each RF cable must be an RG-11 (75 ohms) cable fitted with F-type connectors. The RF cables should already be connected to the antenna baseplate (see Step 12 of Section 2.2, “Mounting the

TracVision Antenna,” on page 29). The following sections explain

how to connect the RF cable(s) to your satellite TV receiver(s) (IRDs).

To connect the TracVision antenna to your IRDs, choose one of the following configurations (based on the number of IRDs you will connect to the antenna):

Option 1 - Connecting One IRD

Option 2 - Connecting Two IRDs

Option 3 - Connecting Three or More IRDs

Option 1 - Connecting One IRD

One end of the RF cable should already be connected to the RF1 plug on the base of the TracVision antenna. Connect the other end of the RF1 cable to the IRD plug labeled “LNB,” “ANT/SAT,” or “SATELLITE IN.”

Option 2 - Connecting Two IRDs

Two RF cables should already be connected to the RF1 and RF2 plugs on the base of the TracVision antenna. Connect the other ends of these RF cables to the plug labeled “LNB,” “ANT/SAT,” or “SATELLITE IN” on two IRDs.

Installation

54-0198

For instructions on RF wiring for TracNet, please refer to the TracNet

Owner’s Manual or Technical Manual.

The IRD that is connected to the “RF1” cable controls which satellite the antenna is tracking.The IRD connected to “RF2” can select different channels on that satellite but not change the satellite selection itself.

Option 3 - Connecting Three or More IRDs

(North American and Latin American Systems)

To connect three or four IRDs to the TracVision antenna, you will need to install an active multiswitch (Channel Master model 6214IFD or equivalent) between the antenna and the IRDs. Two RF cables should already be connected to the RF1 and RF2 plugs on the base of the TracVision antenna. Figure 2-13 shows a typical wiring arrangement for three or four IRDs. Mount the multiswitch unit in accordance with the manufacturer’s instruction sheet.

1. Connect the RF cable labeled "RF1" to the multiswitch input labeled "LNB RHCP +13V.”

2. Connect the RF cable labeled “RF2” to the multiswitch input labeled "LNB LHCP +18V.”

3. Connect the multiswitch outputs to individual IRD inputs. Use RG-11 cable with F-type connectors for all RF connections. Terminate all unused output connectors with 75 ohm DC blocks (Channel Master #7184, Radio Shack #15-1259 or equivalent).

54-0198

TracVision G8 Owner’s Manual - Guide to Technical Information

Option 3 - Connecting Three or More IRDs (European Systems)

Because the European system comes with a quad-output LNB, all four RF outputs from the TracVision antenna can be connected to individual IRDs.

Connecting Three or Four IRDs

To connect a third IRD, a third RF cable should already be connected to the RF3 plug on the base of the TracVision antenna. Connect the other end of the RF3 cable to the plug labeled “LNB,” “ANT/SAT,” or “SATELLITE IN” on the third IRD. To connect a fourth IRD, use the fourth RF cable, which should already be connected to the RF4 plug on the base of the antenna.

Connecting More than Four IRDs

To connect more than four IRDs, you will need to install an active multiswitch between the antenna and the IRDs. Connect the multiswitch unit in accordance with the manufacturer’s instructions. Figure 2-15 shows an example of a European multiswitch configuration.

Connecting the IRD Ground Wire

Agrounding wire has been provided to connect your IRD to a suitable ground. Attach the grounding wire to any suitable screw on the rear panel of the IRD with a good contact with the IRD chassis. The other end should be connected to a suitable ground, ideally to the MCU ground terminal (route the ground wire to the

MCU and leave unconnected for now). Each IRD that you connect to the TracVision system should have a similar ground connection.

If you are using a multiswitch, you can ground the multiswitch instead of the individual IRDs.

2.4 Wiring the MCU

All other wiring for the TracVision system connects at the rear panel of the MCU.

For the TracVision system to work, you must connect the following cables to the MCU:

• Antenna data/power cable

•Vessel power cable

• IRD ground cable(s)

Figure 2-16 shows the MCU’s rear panel connectors. Refer to this figure when wiring components to the MCU.

MCU Ground Wire

Connecting the Antenna Data/Power Cable

Connect the antenna data/power cable to the data/power connector on the MCU’s rear panel (see Figure 2-16). Do not overtighten; finger-tight is sufficient.

Connecting Vessel Power and the IRD Ground Wire

Short circuits may result in severe electrical shock or burns. Turn off vessel power and test the circuit to ensure that no power is present before connecting any power cables. Do NOT reapply

power until all system wiring is completed.

The TracVision G8 system requires an 9-36 VDC power input. Since it does not have a dedicated power control (ON/OFF switch), a quick-tripping circuit breaker or fuse should be installed between vessel power and the MCU. Circuit overload protection should be rated for 30 amperes. For recommended power cable specifications, refer to Table 2-2 on page 22.

A power connector plug has been supplied in the kitpack to make connecting power to the MCU a snap. To connect the power and IRD ground wires, follow the simple steps below.

1. A large ferrite coil is supplied in the kitpack to help reduce conducted emissions from the vessel power cable. This ferrite coil needs to be installed for the system to comply with CE standards. To install the ferrite coil, make two loops in the vessel power cable and clamp the ferrite coil around the loops (see Figure 2-17). The cable, with both positive and negative wires, must pass through the ferrite coil three times to be effective.

54-0198

TracVision G8 Owner’s Manual - Guide to Technical Information

KVH recommends a 24 VDC power input to the TracVision G8 (supplying not less than 9 VDC at the MCU). Power supplied to the TracVision G8 MUST NOT exceed 36 VDC or the TracVision power supply will suffer serious damage!

Before connecting the power cable, turn off vessel power and test the circuit to ensure that no power is present.

Figure 2-17

Large Ferrite Coil Clamped

onto Vessel Power Cable

2. Find the power plug provided in the kitpack and insert your vessel power wires into the plug’s (+) and (-) terminals (see Figure 2-18).

3. If you’ve routed an IRD ground wire to the MCU

(as recommended in Connecting the IRD Ground

Wire on page 35), insert the wire into the plug’s

ground (-) terminal.

4. Secure the wires in place by tightening the terminal screws.

5. After inserting and securing the wires, tug gently to ensure that the connections are solid. Also make certain that the wire insulation is not pinched in the connector.

6. Plug the power connector plug into the power jack on the MCU’s rear panel (see Figure 2-16 on

page 35).

7. Secure the plug in place with the two retaining screws.

8. The MCU has a ground wire preattached to one of its retaining screws (see Figure 2-19). Be sure to connect this wire to a suitable ground.

2.5 Mounting the MCU

Mount the MCU using either of the following options:

Option 1 - Velcro Fastening on a Horizontal Surface

Option 2 - Flush-mounting

The following sections describe how to mount the sensor for both of these options.

Option 1 - Velcro Fastening on a Horizontal Surface

1. Choose a location based upon the guidelines in

“Choosing the Best Location for the MCU” on page 25.

2. Remove the four squares of Velcro fabric from the kitpack. Clean the bottom of the housing with a mild detergent and water to remove oils, etc. Peel the protective backing from the squares and apply them to the bottom of the housing at each of the four corners (see Figure 2-20).

3. Position the four Velcro hook disks where the MCU will be mounted. Drill screw holes for the disks and secure in place with the #4-24 screws supplied in the kitpack.

4. Press the MCU firmly into place so that the loop material engages the hook disks.

2.6 Activating/Programming the IRD

Before it can be used, your IRD must be activated and/or programmed, as described below.

DIRECTV and DISH Network IRD Activation

KVH makes it easy to activate your DIRECTV or EchoStar (DISH Network) IRD. Just call KVH at 1-888-584-4163 and ask for IRD Activation (Monday - Friday, 8:30 a.m. - 5:00 p.m. EST). For other options, please refer to the user manual that accompanied your IRD.

Other IRD Activations

Please refer to the user manual that accompanied your IRD for activation instructions.

Programming European IRDs

Before the TracVision G8 system can be used in Europe, the IRD must be programmed to receive signals from the selected DVB satellite services. Programming is conducted using menu selections displayed on the TV screen. Please refer to your IRD owner’s manual for specific instructions.

Table 2-4 provides some key data for use when programming the IRD.

Configuration Item Setting

Antenna Alternative 1 DiSEqC 1 Antenna Alternative 2 DiSEqC 2 LNB Frequency Universal

It is also important that the IRD’s settings for Antenna Alternatives 1 and 2 match the MCU’s installed satellite settings as follows:

• Antenna Alternative 1 = Satellite A

• Antenna Alternative 2 = Satellite B

Section 2.7, “Installing Satellites Using the MCU,” on page 42

provides details on the satellite installation process.

Table 2-4

Key IRD Settings

When programming the IRD with the antenna configuration data, make certain that your choices for Antenna Alternatives 1 and 2 match those installed as Satellites A and B during the Install Satellite procedure detailed in Section 2.7,

“Installing Satellites Using the MCU,” on page 42.

Installation

54-0198

Programming DSS Plus IRDs

If you are using multiple DSS Plus IRDs and intend to shift from one satellite to another, only one of the IRDs can be configured as a two-satellite receiver. All other IRDs must be configured as onesatellite receivers. The two-satellite IRD will determine which satellite the antenna is tracking while the other receivers can watch any channels available via that satellite. Refer to your IRD owner’s manual for complete details on this process.

If you use an active multiswitch to connect three or more IRDs, the multiswitch will interfere with the 22 KHz tone sent by DIRECTV DSS Plus™IRDs to the antenna. As a result, the antenna will not receive the signal to change satellites when you change channels using your DIRECTV DSS Plus remote.

54-0198

TracVision G8 Owner’s Manual - Guide to Technical Information

2.7 Installing Satellites Using the MCU

The TracVision G8 can track a variety of DVB-compatible and DSS (DIRECTV) satellites. The system contains a preprogrammed library of North American, European, and Latin American satellites. It also has two open slots that you may use to program two additional satellites of your choice. Table 2-5 lists the possible satellite pairs in North America and Table 2-6 lists the satellites that can be programmed in Europe (as long as the paired satellites are within range of the TracVision antenna). Two of these satellites may be selected to reside in the system’s active memory as Satellites A and B. For Latin American systems, either Galaxy_8W or Galaxy_8E can be selected, but not both.

Any two of the European satellites listed below can be paired together, as long as the satellites are within range of the antenna:

• Astra1 • Sirius

• Astra2N • Thor

• Astra2S • Arabsat

• Hispasat • Nilesat

• HotbirdWB • Optus_B1

• Hotbird • Optus_B3

The satellites listed in TracVision G8’s preprogrammed satellite library will be sufficient for most users. However, if you wish to install one or two satellites that are not in the library, skip to

“Programming User-defined Satellites” on page 45. After configuring

these user-defined satellites, return to the satellite installation process in “Installing Your Selected Satellites” on page 43.

Programming User-defined Satellites

The TracVision G8 satellite library has the capacity for two userdefined satellites in case you want to track a satellite that is not currently preprogrammed in the library. User-defined satellites can only be configured via the MCU’s maintenance port. To configure a user satellite, information about the satellite must be provided, including:

• Satellite name

• Satellite position (longitude)

•Transponder information for each of the following polarizations/frequencies:

- vertical high

- vertical low

- horizontal high

- horizontal low

- right

- left

•Transponder information includes:

-frequency

- symbol rate

- FEC code

- network ID (in hexadecimal format)

This information can be obtained from your satellite service provider or from a number of sites on the Internet, such as

www.satcodx.com.

How to tell the difference between High and Low bands:

High: 11.700 - 12.750 GHz Low: 10.700 - 11.700 GHz

For your reference, the satellite configuration information for the predefined satellites is available on our web site at www.kvh.com/

footprint/index.html.

TracVision G8 Owner’s Manual - Guide to Technical Information

Connecting a PC to the MCU Maintenance Port

To program your user-defined satellites into the TracVision G8 satellite library, you need to connect a PC to the MCU’s maintenance port. This procedure requires Windows Hyperterminal (or other terminal emulation software, such as PROCOMM). Use the settings appropriate to your application and follow the steps below.

1. Connect one end of the PC data cable to the DB9 maintenance port connector on the rear of the MCU. Connect the other end to the serial port on your PC (a 9-pin/25-pin connector adapter may be needed for some PCs).

2. Open the terminal emulation software and establish the following settings:

• 9600 baud

• no parity

•8 data bits

•1 start bit

•1 stop bit

• no flow control

3. Apply power to the TracVision G8 system and allow the system to complete full initialization. Data should be scrolling on the PC display to identify any system problems detected. If no data is seen, recheck your connections and the terminal software setup for the correct COM port.

Entering User-defined Satellite Data

To configure your user-defined satellites, follow the steps below.

1. Using your PC’s terminal emulation program, enter the SATCONFIG parser command as follows:

Command: SATCONFIG,USERX,YYY,Z,D,L<cr>

(<cr> indicates a carriage return/ENTER key)

Where: X = 1 or 2 (satellite alternative)

YYY = longitude (0-180) Z = E (East) or W (West) D =decoding type (0 = test, 1 = DSS-A,

2 = DSS-B, 3 = DVB)

L = LNB polarization (C = circular, L = linear)

Function: configures one of the user-configurable satellites

with the longitude provided

Response: if valid entry, echoes the input data

if invalid entry, returns error message

2. Type @DEBUGON<cr> to enter DEBUG mode.

3. Enter the satellite’s transponder information as

follows:

Command: @SATCONFIG,X,N,F,S,C,ID,P,B,D<cr> Where: @SATCONFIG = directs data to the RF Board

X = satellite location A or B N = satellite table # (98 & 99 are slots for user-

defined satellites)

F = frequency in MHz (either 00000 or a range from

10700 - 12700)

S = the satellite transponder symbol rate in

Mbit/second (01000 - 29999) C = the FEC code (e.g., 12, 23, 34, 56, 67, 78) ID = the satellite network ID in hexidecimal format

(0x####)

P = the LNB polarization (v = vertical,

h = horizontal, r = right, l = left) B = the LNB down conversion frequency (l = low,

h = high, G = Latin America, U = USA) D = decoding type (0 = test, 1 = DSS-A,

2 = DSS-B, 3 = DVB)

Table 2-8

Satellite Transponder Data Sequence

Table 2-7

SATCONFIG Parser Command

54-0198

TracVision G8 Owner’s Manual - Guide to Technical Information

4. Repeat Step 3 for each of the following transponder categories:

• vertical high • vertical low

• horizontal high • horizontal low

• right • left

TracVision G8 requires that the data fields for all transponder categories be provided. If the selected satellite does not have information for one or more of the transponder categories, default information should be entered in the fields as follows:

Transponder Data Default Value

Frequency 00000 Symbol Rate 27500 FEC Code the same value as provided for those

transponders with data Network ID 0x0000 Polarity and Band whichever combinations are not

already provided

5. After entering all of the necessary information, save the settings by typing

@SAVE,A<cr> (or B if

the data is for satellite User 2).

6. Type

ZAP<cr> to restart the antenna.

7. If you need to configure a second user-defined

satellite, repeat this procedure starting with Step 1 to enter data for the USER2 satellite.

You have now added your user-defined satellite(s) to the system’s satellite library. The first user-defined satellite you configured is stored as USER1. If you configured a second satellite, it is stored as USER2.

If you want the antenna to track one or both of these user-defined satellites, you need to install it. To install a satellite, you can use either the MCU, as described in “Installing Your Selected Satellites”

on page 43, or you can use the SATINSTALL command, as

described on the following page.

Table 2-9

Satellite Transponder Default Data

Installation

54-0198

1. Type HALT<cr> to put the antenna in Idle mode.

2. Enter the

SATINSTALL parser command as

follows:

Command: SATINSTALL,<sat_a_name><sat_b_name><cr> Where: <sat_a_name> = the name of your choice for

Satellite A (for example:USER1) <sat_b_name> = the name of your choice for

Satellite B (for example:USER2)

If you only want to install and track one satellite, enter

NONE as the name of Satellite B.

3. Once you’ve assigned satellites as Satellite A and Satellite B, you need to tell the antenna which of the two satellites it should initially acquire and track. This step should be performed the first time a satellite is selected, allowing the system to download the channel guide. To do so, enter the following parser command:

Command: @L,x<cr> Where: x = A or B (whichever satellite you want to track)

4. Type ZAP<cr> to restart the antenna.

Examples of the user-defined satellite configuration process are provided for reference in the next two sections.

European systems only:

If DiSEqC is active on your IRD, once the antenna restarts, the antenna starts tracking the satellite currently selected by the IRD, overriding the @L,x command.

Updating Satellite Frequency Data

If the antenna is unable to find a satellite, the satellite’s frequency data may have changed. The Satellite Frequency Scan feature allows you to update the frequency data of any satellite stored in the system’s library.

This function should not be used unless directed by KVH Technical Support or a KVH-authorized technician.

With the desired satellite, band, and polarization selected, the system will automatically search for the frequency with the strongest signal. The system will then update that satellite’s programmed data with the new frequency (and associated network ID) and store it in the satellite library.

To update the satellite frequency data, follow the steps below:

1. Place your IRD in the satellite signal meter mode.

2. Select the desired satellite on the MCU. Ensure the

TV signal meter indicates that you have a strong signal.

If the antenna is unable to find the selected satellite automatically, you can manually point the antenna using the Manual mode (see “Manually Controlling the Antenna” on page 69).

3. Select the desired polarization and band on the IRD.

4. Do not move the vessel. Your boat must remain motionless during the entire Satellite Frequency Scan process.

5. Follow the MCU menus on the next page. The scan itself will take a couple of minutes. Once complete, restart the antenna and ensure the antenna will track the new frequency.

Control Compass Mode

The Control Compass function allows you to turn autocalibration on/off, read the calibration score, and clear the calibration.

Selecting Autocalibration

Every antenna’s internal sensor module is calibrated at the factory in a perfect-world environment. However, hard and soft iron effects on your vessel can distort the local magnetic field, causing errors in the reported heading. These errors are minimized by mounting the antenna in a suitable location and are further removed by the system’s autocalibration feature, which compensates for minor magnetic distortions while your vessel is moving. The more the vehicle moves with autocalibration turned on, the more accurate the sensor will become.

TracVision G8 Owner’s Manual - Guide to Technical Information

4.2 Causes and Remedies for Common Operational Issues

There are a number of common issues that can affect the performance of the TracVision G8. The following sections address these issues and potential solutions.

Power Disturbance, Blown Fuse, or Low Power

Power Disturbance

If the MCU detects a power disturbance, such as a voltage spike, the system shuts itself down. If this occurs, simply disconnect power from the MCU,

wait 20 seconds, then restore power.

Blown Fuse

The antenna unit is equipped with a 5-amp, 125-volt fast-blow fuse on the PCB module. The MCU is equipped with a 30-amp, 125-volt fastblow fuse on its rear panel. If either of these fuses has blown or been broken, the system will not work. To access the MCU fuse, simply unscrew the fuse holder cap on the rear panel. For details on accessing the antenna’s PCB module fuse, refer to “Replacing the PCB Module Fuse” on page 96.

Low Power

If the data/power cable from the antenna unit to the power source or MCU is more than 50 ft (15 m) in length, the power level can decrease over the course of the cable, resulting in a voltage level at the antenna unit that is too low to power the system. Refer to “Connecting Vessel Power and the

IRD Ground Wire” on page 36 for details on

supplying adequate power to the antenna unit.

Figure 4-1

MCU Fuse

Fuse

Improper Wiring

If the system has been improperly wired, the antenna unit will not operate correctly. Refer to Section 2.4, “Wiring the MCU,” on

page 35 for complete system wiring information.

Vessel Turning During Startup

If the vessel turns during the two-minute startup sequence that occurs immediately after turning on the power to the TracVision G8, the antenna will record that variable motion as “standing still.” This may cause the antenna to track improperly. To solve this problem, turn the TracVision G8 off for at least 10 seconds. Turn the system back on, ensuring that the vessel is either motionless or traveling in a straight line for the two minutes immediately following power-up.

Data/Power Cable Interference

Depending on how cables are routed, conducted emissions from the system’s data/power cable may cause reduced picture quality on your TV screen. If the picture quality degrades only when the TracVision G8 is operating, try installing the small ferrite coil supplied in the kitpack. Simply clamp it onto the data/power cable to reduce its conducted emissions (see Figure 4-2).

Incorrect Satellite Configuration

(European Systems Only)

The satellite configuration on European IRDs must match the satellite settings on the TracVision G8 system.

• Satellite A on the TracVision G8 must be the same satellite as IRD Alternative 1 (or A, based on your IRD) and must be assigned the IRD DiSEqC 1 setting.

• Satellite B on the TracVision G8 must be the same satellite as IRD Alternative 2 (or B, based on your IRD) and must be assigned the IRD DiSEqC 2 setting.

Refer to your IRD user manual for complete instructions on configuring your IRD.

Troubleshooting

54-0198

Figure 4-2

Small Ferrite Coil

Satellite Signal Blocked

Satellite signals can be blocked or degraded by buildings, other vessels, or equipment on the vessel itself. Refer to “Choosing the

Best Location for the TracVision Antenna” on page 23 to make certain

that the TracVision G8 antenna unit is in the optimal location. Simply moving the vessel to clear an external obstruction will also restore signal quality.

Satellite Coverage Issue

TracVision G8 will provide outstanding reception within the 32" (82 cm) antenna coverage area for your satellite television service of choice. However, signal quality can be degraded as you approach the fringe coverage areas. Refer to your satellite television service manual to check the viable coverage area for a 32" (82 cm) antenna.

Radar Interference

The energy levels radiated by radar units can overload the antenna’s front-end circuits. Refer to “Choosing the Best Location

for the TracVision Antenna” on page 23 to make certain that the

TracVision G8 antenna unit is in the optimal location with regard to your radar unit.

Satellite Frequency Data Changed

If some channels work, while one or more other channels do not, or the antenna cannot find the satellite, the selected satellite’s frequency data may have changed. To update this frequency data, refer to “Updating Satellite Frequency Data” on page 74.

Incorrect or Loose RF Connectors

As part of preventive maintenance (described in Section 5.2,

“Preventive Maintenance,” on page 93) KVH recommends checking

the antenna unit’s cable connections. A loose RF connector can reduce the signal quality. In addition, if you are unable to switch satellites using your IRD remote, make sure that your IRD’s RF cable is connected to the antenna’s RF1 baseplate connector (see

Section 2.3, “Connecting the IRD(s),” on page 31).

54-0198

TracVision G8 Owner’s Manual - Guide to Technical Information

For your convenience, KVH provides links to several web sites that offer satellite coverage information. Simply go to our web site at www.kvh.com/footprint/

index.html.

Type of Multiswitch Used

An active (not passive) multiswitch must always be used to connect the TracVision G8 system to multiple IRDs. Refer to

Section 2.3, “Connecting the IRD(s),” on page 31 for directions on

proper multiswitch/multiple IRD cabling.

4.3 IRD Troubleshooting

The IRD that was provided with your satellite television service may also be the cause of less-than-ideal operation. First check the IRD’s configuration to ensure it is set up for the desired programming. In the case of a faulty IRD, refer to your IRD user manual for service and warranty information. If the IRD is both configured properly and fully functional, contact your local KVH dealer or service center for assistance.

4.4 Antenna Gyro and LNB Faults

Section 5, “Maintenance,” provides detailed instructions for

authorized service personnel who may be required to replace one of the antenna gyros or the LNB.

Troubleshooting

54-0198

4.5 Computer Diagnostics

TracVision G8 has been designed to provide diagnostic readouts viewed on a PC having an RS-232 serial communication port. If you are unable to isolate a system problem, set up for computer diagnostics as described below. System problems will most likely be found somewhere through the diagnostic readouts.

The diagnostics procedure requires Windows Hyperterminal (or other terminal emulation software, such as PROCOMM). Use the settings appropriate to your application.

2. Open the terminal emulation software and establish the following settings:

• 9600 baud

• no parity

•8 data bits

•1 start bit

•1 stop bit

• no flow control

21. Calibrate the antenna gyros as explained in

“Calibrating the Gyros” on page 105.

22. Reinstall your selected satellites as explained in

Section 2.7, “Installing Satellites Using the MCU,” on page 42.

5.7 Replacing the RF PCB

1. Disconnect power from the antenna unit and the IRD.

The RF PCB is protected within a metal enclosure that is fastened to the antenna frame. This PCB module, which contains the main PCB and the RF PCB, must be removed to gain access to the RF PCB.

2. Disconnect all cables from the bottom of the PCB module, including the roll gyro cable at the in-line connector.

3. Using a

⁄16" wrench, carefully disconnect the RF

cables from the top of the PCB module.

4. Loosen the four captive screws securing the PCB module to the antenna frame. Remove the PCB module and bring it belowdecks for bench work.
